Personally, I continue to think energy is THE penultimate issue. Ecosystem is a vital second, but if we have to decend to nuclear war to settle the issues of insufficient oil and other energy, I'm not sure 'ecosystem' concerns matter too much to many of us.
But this is very sobering. Even with a dramatically lower population of humans, how can things possibly work out? By that I mean, mostly, that the metals required for current PV panels and electric batteries seem to REQUIRE a global supply chain to get the required metals to build ANYTHING sustainable.... And that implies billions of people still living on the earth to do all that mining and transport of the seldom-considered inputs.
I don't know what to do. And, at the same time, I am upset with myself that I am not trying to do SOMETHING.
